The Doomsday Monastery

War is the catalyst for the development and reproduction of civilization in the universe. As small as a field or as large as the universe, big fish eat small fish, and small fish eat shrimps. This is the eternal law of the world of the jungle and the strong! The outbreak of World War III reduced the earth to a Death Star, filled with monsters mutated by nuclear radiation. The surviving humans lingered in the underground world, struggling to survive in the apocalypse. Both blessings and misfortunes are due to these mutated monsters, which enable human beings to start the path of spiritual practice. Let's see how the protagonist creates opportunities to break through the nine heavens and enter the real world of practice.
